We report here the synthesis of new ligands of the aroylhydrazone family. Glyoxylato-aroylhydrazones (gly-AH) with lipophilic character were designed for possible biological applications where metal chelation is desired. They were found to coordinate

Engineered protein-based sensors of ligand binding have emerged as attractive tools for the discovery of therapeutic compounds through simple screening systems. We have previously shown that engineered chimeric enzymes, which combine the ligand-bindi
